 1) After the proposal was executed (#1937365), how quickly did the new validators show up?  
 **It took around 10 days (05/02/20-15/02/2021) for the number of validators to grow from 47 to 80.**

 4) Did the number of network nodes increase 'proportionally'? (Might be hard to figure out, unless you've configured your node to accept >80 peers.)  
 **Since no data was saved about the peers, the data from the active and waiting validators were used.  
-    As can been seen in the Validator Status graph the number of nodes increased drastically.

 6) Was there a spike in tokens staked, or were they just shifted?  
-**Looking at the graph of the Validators Stake by Date it's possible to see some spikes, up and down, in the amount of tokens staked. 
-Maybe due to the attempts of keeping the 25% total amount of staked tokens in order to maintain the best validator rewards.

 8) Anything else that was noteworthy?  
-**It seems that the new validators increase the max and min block time, but the max block time decrease at the end which may indicate that the servers used for validating were improved. The increase of the block time was felt since it delayed the council election and increased the active council round.   Would also be good to collect the percentage of validators stake to check if the changes in the rewards were influenced by the percentage being close to 25%**
